The biggest flaw of Oblivion was that people who did not like tried to rebound by running off to any "niche" or "hardcore" forum they could find, so they talk endlessly how much they hated the game.
These people knew less of old games and their merits, and were only trying to earn an oldschool label simply because they disliked a new game.
In short, it has created a generation of fucking posers, people who aren't here to celebrate what was good about old games, but rather to deride new ones. Their idea of finding likeminded people has only been based on a negative fulfilment, rather than a positive and honest reason to come to niche RPG message boards.
The most amusing thing about posers is that their idea of an old game is a game made within this very generation, and how they try to wax nostalgic about it, as if those games were made aeons ago.
Equally amusing about such posers is that when they find people who are playing and enjoying new games, they try to deride them for it, not even realizing that many of those said people have far more knowledge and experience of games of many generations.
So they assume that pre-emptively hating new games is cool and trendy, not realizing that many genuine oldschoolers are able to enjoy new games just as well as they can enjoy old ones. It is something they can never grasp, and in their pathetic state, they envy people who are able to derive more enjoyment from games than they do. The best they can do is regurgitate buzzwords, that have no meaning whatsoever, while some people are genuinely enjoying the games they find
And all these posers; their minds explode at the notion that while these people know and understand old games, they do not mind catching up on some new games, and do not mind upgrading their computers for new age games. Somehow, it is impossible for the posers reconciliate the idea that even niche gamers can admire the products of new technology.
Hence, these posers, who want to compensate the inferiority complex borne out of having a crappy PC, are in a sad state where they neither understand or know of old games nor are able to enjoy new games.
This is what Oblivion did.
